Abstract
The authors report their experience with 14 patients with portal vein injuries (1976–1986) treated at a level I trauma center. Seven patients (50%) survived and included six of 10 patients (60%) who had venorrhaphy and one in whom the portal vein was ligated. Associated injuries were present in all the patients (mean Abdominal Trauma Index: 39.5) and accounted for the high mortality rate. Follow-up data after repair or ligation of the portal vein seldom are reported in the literature. The authors studied all three patients who survived portal venorrhaphy since 1982 by real-time ultrasonography. Patency of the repair could be established in two patients. In the third patient postvenorrhaphy thrombosis was diagnosed by ultrasonographic examination. Sequential ultrasonographic examinations demonstrated resolution of the thrombus on anticoagulant therapy. Ultrasonography provides a noninvasive and easily reproducible method of studying the portal vein after repair.
